EZero Technologies LLCGreen Energy Solutions for Electronics

our mission

Ezero Technologies is dedicated to providing solutions to the problem of powering portable electronics
and wireless devices in a manner which can reduce environmental impact. Primarily these solutions relate to
increasing battery lifetime through energy recapture technologies or to eliminating batteries altogether in
many applications.

As is well known batteries represent a significant environmental problem as a source of toxic heavy
metals and safe disposal is a difficult problem. Extending battery
lifetime can reduce this impact. Even more significant is the ability to eliminate batteries altogether in
a large number of applications.

Significant collateral benefits include improved convenience for users who have to replace or
recharge batteries and elimination of wires in many applications ("Zero Energy Wireless"). Ezero Technologies
has core patented and patent pending technology to make this possible and is focused on implementing this
technology and working with licensees to find optimal solutions for their portable and wireless applications.

technology application areas

Ezero's proprietary technology is directed to core solutions for reducing
or eliminating batteries and their negative impact (including user inconvenience, such as
battery cost, recharging/replacement/failure, weight, size, etc.; and extensive environmental
impact) in many application areas. These may be generally grouped in three main areas:
1. Battery-free wireless keyboard solutions, 2. Energy harvesting for mobile devices, and 3.
Battery-free home control solutions. It is now literally possible to dramatically reduce battery use at
home and elsewhere while increasing convenience and reducing cost.

Energy Harvesting for Mobile Devices

Battery-Free Home Control Solutions

Tablet Convertible

Near field communication (typically using 13.56 MHz RF magnetic coupling) is emerging as a
game changing new communication mode for smart phones and tablets. This is due to a number of applications
including effortless device pairing, information sharing, secure payment transactions, downloading info
from "smart posters" and retail outlets, and many other applications yet to come.

A significant collateral benefit is that a tablet with built-in near field communication can be effortlessly
turned into a notebook or mini desktop by using Ezero's patented and patent pending technology.

A passive keyboard is powered from the near field RF link and can be ultra light, ultra thin, inexpensive
and battery free giving all the benefits of a keyboard for the tablet whenever needed. Since it is battery
free it is always ready and ideal for portable use.

No change in the tablet design is needed. No electrical connections are needed to the tablet or to the
keyboard. If a notebook is desired a patent pending passive hinged tablet/keyboard holder can be used.

Battery-free Desktop Keyboard/Mouse

Wires are a headache in any desktop computer. A wireless keyboard and/or wireless mouse is a big help
but replacing batteries in a wireless keyboard or wireless mouse is also a headache.

Home Control

Wireless Light Switch

Ezero's patented wireless transmission using energy harvested from pressing a button can power wireless
control of a light switch or other device (powered shades, air conditioning, etc.) without batteries.

Installation is easy since wiring for supplying power to the switch is unnecessary.

Since no batteries are needed battery cost and replacement inconvenience are avoided while helping the
environment.

Battery-free Remote Control

Ezero's patented wireless transmission using energy harvested from pressing a button can power a remote
control for a TV or other component without batteries.

Since no batteries are needed battery cost, weight and replacement inconvenience are avoided while
helping the environment.

An alternative solution can use RF energy reflected back by the remote to a transmitter/receiver in the TV -
referred to as backscatter RF communication. This can be battery free for typical ranges needed for remote
control. Ezero also has patented and patent pending solutions using this approach.

Wireless Game Controller

Wireless game controllers are notorious for using up batteries.

Ezero's patented energy harvesting using energy harvested from pressing a button can be used to power a
wireless game controller.

Depending on the controller no batteries may be necessary. Alternatively the push button energy harvesting
can recharge a game controller rechargeable battery during use lengthening time between charging.

Wireless Door Sensor

Ezero's zero energy wireless transmission using energy harvested from a mechanical movement
such as a spring loaded door or window sensor can power wireless alarm activation.

Installation is easy since wiring for supplying power to the sensor and transmitter is unnecessary.

No batteries are needed so battery cost and replacement inconvenience are avoided while helping the environment.

Smart Phone with Energy Harvesting Buttons

Ezero's patented mobile device recharging using energy harvested from pressing a button can help power
a smart phone.

Smart phones are more and more being used as portable games which can use valuable battery lifetime. But
push button energy harvesting can recharge the smart phone battery during game use lengthening the
time between charging.

Push button energy harvesting can also provide emergency short term power for a short call or text if
the battery is dead and recharging is not possible.

Battery-free Medical Monitoring

Many new approaches to continuously monitoring key health and medical condition parameters are becoming
available. These are becoming smaller and smaller and can be worn. Ideally the readings are read out as
desired and sent, for example, to a PC or remote monitoring link. The worn devices must be small,
unobtrusive and reliable. The problem is how to power these devices. Small batteries can be used but
they cannot last indefinitely.

Energy harvesting using a simple button press to send a wireless signal to the home based monitoring link is
a natural solution. Ezero's patented technology makes this possible potentially enabling a new era of home
health monitoring. Alert signals can similarly be sent to link to a remote monitoring location by a button
press without worrying that a battery has failed at a critical time.
